-finline-stringops: check base blksize for memset [PR112778]
The recently-added logic for -finline-stringops=memset introduced an
assumption that doesn't necessarily hold, namely, that
can_store_by_pieces of a larger size implies can_store_by_pieces by
smaller sizes. Checks for all sizes the by-multiple-pieces machinery
might use before committing to an expansion pattern.
